Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keratinous fiber treating agent composition for imparting a good firmness and firmness to keratinous fibers such as hair and a method for treating keratinous fibers using the same.

[0002]

2. Description of the Related Art Conventionally used methods for modifying keratinous fibers, such as hair, wool, and fibers for knitting and knitting fabrics, include (1) perming agents and polymers added to hair dies. By adsorbing to

No. 60-87208), and (4) a method of adding a water-soluble substance to keratinous fibers to form a substance insoluble or hardly soluble in water in the fibers (JP-A-1-233208). ing.

[0003]

However, these conventional methods for modifying keratinous fibers have some problems.

That is, in the above-mentioned method (1), since all the polymers and the like used are effective by adsorbing them on the surface of the hair, it is easy to wash them with a shampoo that does not contain them. The effect disappears. Further, in the method (2), since the molecular weight of the protein hydrolyzate used is usually several thousand or more, the amount of the protein hydrolyzate to be filled inside the hair is very small, and the effect is not sufficient. In the method (3), a metal ion or the like is used as an astringent agent, and the effect of this astringent agent is caused by chelation of the metal ion and a functional group (mainly a carboxyl group) in the hair. . Therefore, washing with a general shampoo containing a chelating agent such as sodium ethylenediaminetetraacetate causes a chelate exchange reaction, and the effect is gradually lost. Further, in the method (4), a certain amount of firmness and firmness can be imparted, but the effect is not yet sufficiently satisfactory.

As described above, the conventional method for modifying keratinous fibers has not been satisfactory in terms of its modifying effect.

Therefore, there has been a demand for the development of a novel keratin fiber treating agent composition which imparts excellent elasticity and firmness to keratin fibers and a method for treating keratin fibers using the same.

[0007]

In view of the above situation, the inventors of the present invention have conducted extensive studies to solve the above-mentioned problems, and as a result, the first agent containing an organic solvent and an acid is combined with the acid to be insoluble in water. Alternatively, when treated with a keratinous fiber treating agent composition comprising a second agent containing an inorganic cationic substance forming a hardly soluble salt, a hardly soluble or insoluble salt is precipitated in a large amount of water in the keratinous fiber. However, the keratinous fiber has a sufficiently high elasticity,
The present invention has been completed by finding that it gives a firm feeling.

That is, according to the present invention, a first agent having an organic solvent and an acid and having a pH of 2 to 5 and an inorganic cationic substance which binds with the acid to form a water-insoluble or sparingly soluble salt are used. A two-component keratinous fiber treating agent composition comprising more than 5 second agents.

The organic solvent contained in the first agent of the composition of the present invention is used for the purpose of uniformly dissolving the acid described below and promoting the permeation of the acid into the keratinous fibers. Examples of such an organic solvent include those represented by the following general formula (1) or general formula (2).
